ASoC: atmel: fix build error with CONFIG_SND_ATMEL_SOC_DMA=m
If CONFIG_SND_ATMEL_SOC_DMA=m, build error: sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio': (.text+0x7cd): undefined reference to `atmel_pcm_dma_platform_register' Function atmel_pcm_dma_platform_register is defined under CONFIG SND_ATMEL_SOC_DMA, so select SND_ATMEL_SOC_DMA in CONFIG SND_ATMEL_SOC_SSC, same to CONFIG_SND_ATMEL_SOC_PDC.
